XBMC vs. NextCloud

XBMC vs. NextCloud

Right now I am successfully running NextCloud 10 on Bananian, using Nginx as webserver. I would like to use my Banana Pi as a media server as well to watch movies via the HDMI output. I tried to install the XBMC version from the repository, but that version keeps on crashing.

Then I downloaded the XBMC image provided by LeMaker, wrote it onto a second sdcard and startet the Banana. To my surprise, that version runs smoothly and without crashes. I tried to find differences between the two versions of XBMC, but after a fiew hours I gave up.

My question now is this: will Nginx and NextCloud work on the Linux version that the XBMC-image provides? Are there any traps that need to be avoided?

Well, my question was aiming more towards this direction: is the XBMC image just another Linux system, that happens to include a specialized version of XBMC/Kodi and maybe some special kernel code and modules, but that will behave like normal Bananian otherwise, or is it a special operating system that doesn't have any repository and that doesn't accept third party software?
